SOFT DECISION DETECTING METHOD AND APPARATUS OF MULTIPLE-INPUT MULTIPLE-OUTPUT COMMUNICATION SYSTEM |
| 摘要 |
A soft decision detecting device in a multiple-input multiple-output (MIMO) receiving apparatus detects reception symbols from signals received through a plurality of reception antennas, calculates a variance of interference and noise of the detected reception symbols, and soft-decision-demaps the detected reception symbols by using the variance of interference and noise of the detected reception symbols to thus calculate a soft decision value. |

1. A soft decision detecting method in a multiple-input multiple-output (MIMO) receiving apparatus, the method comprising:
receiving symbols, transmitted through a plurality of transmission antennas, by a plurality of reception antennas; detecting each reception symbol from signals received through the plurality of reception antennas; calculating a variance of interference and noise of the detected reception symbols; and soft-decision-demapping the detected reception symbols by using the variance of interference and noise of the detected reception symbols. |
